Answer 1

Just in case someone is affected by this problem and stumbles on this post 4 years later: in my case the module had a small "sticker" type antenna and it got somehow damaged.

I could connect to the network but when I tried to use HTTP over the GPRS networks I only got return code 601 (network error) or 603 (failed to resolve DNS).

Once I replaced the antenna with a new one, everything worked perfectly.
